There is aseries of these siib-levers 23 each consisting of a :le-ver ofthe first ,order pivoted at 24 in ahenger.

' shaped series, which will be understood from middle ot the machine to get said sub-lever substantially into the plane or. the corresponding type bar7 as shown in Fig. .fl at This applies solely, or .at least more especially. to` those sub-levers that are. considerably removed from the middle of the machine.

The upper endsmf the sub-levers are arranged in au are substantially correspond ing with the arc of the pivots 20 in the heels of the type bars and the'lower ends of said sub-levers are preferably arranged in straight line across the machine. Thevsulr' levers therefore are of varying lengths, those near the middle ot the machine heing shortest andthose near the sides of the machine being longest. ln order to main sul'istann tially the same leverage throughoutthe sys;-v

tem the hangers 25 are arranged in an are Fig. fl, which shows the series of holes 27S.

The sub-levers 7" are operated at. their lower ends by links 3l each pivoted to thesub-lever at' 32 and extending from .sa-id pivot approximately horizontally toward the rear, being pivoted at 33 to the rear end of a substantially horizontal key lever 34- of the lirst order, said key lever being pivoted between its ends at and carrying a key 36 at its for ard end. The links 3l are comparatively short, as shown, and when one ot the keys 3G is depressed to move the pivot point upward to the position shown in broken lines `in Fig. S, the sub-lever 23 and parts connected therewith are operated, throwing the type bar to the printing position. ln order to avoid conflict between the key lever and the lower end of the sublever, said key lever is formed at its rear' end with a substantially upright section 3 7.

The keys 36 are arranged in tour rows as usual as shown in Fig. l and in order to give all ot them the same leverage relation to the rear ent s of their. respective key levers 34. the pivots-3:3 'of said key levers are arranged in four banks as will be understood from Fig. l, the key levers whose keys 36 are in the rear end of the keyboard being pivoted on the rear wire 35; those key levers whose keys are in the second row being pivlted on the second'wire 35, and so on. To this end a rib 38 is formed on or secured to the underside of the plate? extending across the machine, and said rib has a series of slots renace i 39, Fig. 4, out therethrough in a front and rear direction, one :for each ot the key levers 34. As shown in Fig. 3 four holes l() are drilled .through the rib 38 and ,the tour wires are put through said holes. Each of the key levers has an ear Lil formed at a suitable point at its upper edge and said ear lies in one of the slots and is pivotedv on one of the wires @ther means may of course, if preferred, be provided for inserting the wines 35 than by drilling holes the length of the rib 38. Each of the key vlevers has a downwardly extending arm 4t2 to which is connected the rear end of a restoring spring 43. The said springs have their forward ends connected vto a row ot hooks elle formed on the edge of a har l5 se cured by screws 46 to the base l of the frame.

By provit ing the four pivots 35, one for each oi the transverse vrows ol' keys 36, and by arranging the pivots le of the subdevers 93 in the manner that has been explained, it will be seen that all of the key levers have the same dip and the saine leverage on their respective type bars, and that the upper ends of all of the sub-levers move through the same distance when operated.

ln the Patent No. 98?:,7lh dated .eceur ber 2l, 19M, l have shown type bar operating mechanism having some of the characteristics of the present mechanism and some of the advantages of thev present n'iechanisin, but my present mechanism is' an improve ment over that shown in the patent. .ln the patent the key levers are connected by short links with upright sub-levers but said short links extend from the rear ends of the key Ilevers toward the rear of the machine and rock the sub-lever, when a key is depressed, in Ya direction the opposite to that illustrated in the present case. ln the patent the upper ends of the sub-levers are conneetedby pull links with the type bars, said links being pivoted to said type bars above or inside oil the type bar pivots. The result oi this is that tlieupperends of said sub-levers are arranged in an arc that is or less radius and of less width than the row of type har pivots and ot considerably less width than the system of key levers. This difference in width between the system of key levers and the upper ends of the sub-levers was compensated tor in the patented construction by setting said sublevers on a slope, those near the sides ot the machine inclined inward at their upper ends, with the result that the plane of motioeot the key lever did not corre-7 spend with that oi the subdever. ln the present instance, by connecting the links 9,1 with the type bars below or outside the pivotsot said type bars, the upper part ot the system of sub-levers is about wide as the system of key levers. The sub-levers are therefore all approximately vertical. l

llo

'have also found by experiment that by the extending rearward from the sab-levers and yof the screws 52.

making the links 21 pus'h links instead of' pull links, I- get an improved action. By the present arrangement I avoid crowding the upper ends of the sub-levers and opportunity is afforded to make all the mechanism more `substantial and accessible, and also find by experience that the present connections from the key to the type. bar give a better action in use than those ofthe patent.

, I have provided a very light, simple and effective shifting segment construction. rIhis mechanism includes a frame best chown in Fig. 6 and' which consists of two end bars or pieces 47 and a cross bar 48,

the latter being made stiff andrigd and being rigidly connected 'withm the former, Preferably-this entire frame consists of a single integral piece. -The arms 47 are approximately horizontal and are pivoted attheir rear ends on pivot screws .50 threaded into lugs 51 projecting from the rear posts 4. The right-hand lug 51 is-shown. broken away'in Fig. 6 in order to disclose other parts of the mechanism. At their forward ends the arms 47 are formed with threaded holes into which are screwed combined pivot and stop 'screws 52, as perhaps best shown in Fig. 4. Each of these screws" has a reduced inner end.53 which projects into a hole 54 in the end of the segment 13the two holes 54 at Ithe two ,ends of the segment being in line with each other. of the segment are trued up and abut against the inner surfaces of the arms 47 so that transverse motion of the segment is prevented.

'screws and 56, the screws 55 beinglabove and the screws 56 being beneath the heads Said screws 55 and 56 are threaded through brackets 57 secured to the underside of the top plate 5. Each of these brackets 57 comprises a vertical part andy two horizontal projecting ears through which latterithe screws 55 'and 56 are threaded. The vertical part of each of the brackets 57 either contacts with or is very close to the end of the corresponding v`formed at its `forward end with the same vsaid typerest is supported by arms 65, The ends' The construction is such that said segment 1s pivoted inthe frame 47, 48 on' `pivot 73 as the guide link 72.

sition in any suitable way. The forward end of the guide link 58 may be pivoted to the segment 13 vin any suitable manner. As here shown (Fig. 6) said guide link is sort of strap: 19 as the heels of the type bars, 75

said strap being split-at one point and being provided with a screw 17 like those of the type bars and. said link is pivoted tothe segment a ball bearing which occupies the middle' one of the grooves 14 of the segment. It will of course be understood that it is not essential that this link be pivote'd to the segment by a ball bearing but the form of the segment is such that that is as convenient away as any to pivot it.

,A spring 62 is connected at its lower end tothe guide link 58 and at its upper end to the top plate 5, and this spring normally holdsl the segment 13 and the parts asso-4 ciated therewith in their upper positions, as 90. shown, for example, in Fig. 4. Shift key mechanism to be presently described, is pro, vided forpulling the Isegment clown to its lower position for upper case Writing.

' The typebars 12 near their free ends normally rest against a type rest 63 having a; pad 64. In order to shift this type rest upand down with the'segment 13 and vin a substantially constant relation 'to said segment,

which at their rear ends' are secured to np- .right bars 66, each at its upper end pivoted at 67 to an ear 68 extending 4downward from the forward end of one of the arms' or bars 47. The bars 66 extend down through v4105 holes 7 0 (Fig. 4) in the plate 2 and just be- Y neath said plate (Fig. 7) each of said bars 66is pivotedat 71 to the forward end of ,a guide link 72,.;Which guide link is substantially parallel with the bars 47, being piv- Y oted at its rear end at 73 toa lug 74 depending from the plate 2. These guide links 72, acting on the lower ends of the barsv 66, and the arms 47,' acting on the 'upf per ends of said bars, maintain said bars in substantially a vertical position, the' bars shifting down and np with the type bar segment and ycausing the type rest' 63to shift correspondingly.

In order to shift the segment downward, 12. a case shift key 75 is provided in the keyboard and mounted on a lever 76, Figs. 3,' 4

'and 7, which lever' at its forward part corresponds inv outline with the key levers 34 and at its rear end is pivoted on the samey Each of the shift key levers 76 is connected with one of the bars 66 by means of a short link or con necting'piece 77. The construction is such that when either one. of the keys 75 is de-- 130 pressed if otlls the segment i3 lowi'i to its" t i upper ease position, as will be unclefstoocl from the above description.

instead of. part the construction above ries'eiibeci. the modification shown in Fig. S may be emiiloyed. iccoifling to this moet i'ication-the guide link 72 is dispensed with and the real' eiitl of the shift key leveil Tf is pivotecl at '755, amil said lever is coniieote filiiectly at 7l. to the lovei" end of the. bar 66. iii this coiistiaiotioii the iea'if ood of the key lei/'ei' 2'6 serves as a guide link for the loweia eetl et the bor 66.

The universel. bai' iiiechsaism for the eerriage esca-pement, is best shown in Figs. 2, 3 and el. Each of the posts et has a bracket T8 piojeetiiig thei'efrom toward the i''ont ot the machine and another biaclet or lug 79 projecting' theref'roi'e ti'iwaicl the tesi'. transverse horizontal. rook shaft SO is piv'otetl vin the toiw'aicl lugs 7@ ancla similial rock shaft Si. in the i'eai lug" The rock shaft 80 has neat its encls iiprigit arms S2, which7 asshowii in Figs. and 1l, are pivoted at their upper ends at 83 to brackets Si projecting from e.. .curved oi' segmental mit if'eisal bar 85, lying" in. the paths of the up per ends of all of the subleveis .Ai/iother broek).l S6 piojects towaicl the ieai of the machine from the universal bat near each enel thereof and the reale eiicls of these brackets oi* ai'ms SG are pivote/(l at 87 to the upper' ends of arms 88 piojeoting` upward from the roclf. shaft Sl.

It will be perceived that by the construction shown and described the tivo rock shafts S and 8l are connected togethei so that theyv aie compelled to rockl in iinisc-ii: anfl that the trame coi'iiprisiug the universal. bai 85 and the brackets 84; al-tl is rigidly mounted aiiil guicleil so that all parts of the universal hat' move in parallel lines and to the same extent.

Any suitable i'estoii spifiii may be pio viilecl to move the iiiii.ersal bar toWa-iil the rear et the machine, to its normal position.. As hei'e shown, a sp1-ing 90 is coilecl about the sliaft 8l and. beats at one emi against the stationary framework and at the other against one ot the aims S8.

I have shown a space bar 107 mounted on theaforward: ends of lever' arms 108., each of Whichat its rear end is pivoted at 10,9 to a lug 110 depending from the plate 2. Each o the-levers 108 is connected by a vertical link 111-with an arm 112 projecting forward from` the rock shaiit'SO. Each of the links 1-11 passes through a suitable hole 113, Fig. and each of them at its upper end is bent ofi so as to pass through a vertical slot 114 in the arm 112. .'lhe construction is such that if the space bar 107 be depressed, the universal bar and its connections, including the feed vdogs 92, will be operated. But if the universal bar and said connections be operatedv by one of the sub-levers 23, thc slot 1111 will move idly with relation to the link 111 and the spacey .bar will not be depressed. 4Any suitable restoring springs may be provided lfor the levers 108. y

'Ihe top plate 5 may be curved upward, as

shown at 115, to serve as a. dust guard and deiiector to catch the dust of erasures, and to prevent it trom falling over into the type bar bearings. It will benoted that all of the rest of the mechanism is thoroughly protected from falling dust. The top plate. itself protects the sub-lever systems, the shifting mechanism and the universal bar mechanism, and the key levers and other parts in the base of the machine are protected by the plate 2, whose dimensions are extended for the purpose. It will be' noted that the solid part of this plate comes under the open part oi. 'the top plate. The prin cipal opening through the plate 2 is that at 116 where the sub-levers project' through it and this is in behind the' liange 27, and underneath the solid part of the. top plate 5. It will be seen that the system' ot' dust protection in this machine is unusually complete.

It will be noted that the construction isV such that both the top plate 5 and the base 1 vcan be removed, and all of the working is an important feature from the manutac parts of the type action remain' intact. This vturing point of view as the mechanism can be assembled and adjusted in this manner.

The casel shiftmechanism, including the shiftingY segment construction and its connections, is not claimed herein but is claimed in my application, Serial No. 759,879, filed April .9, 1913,which said application is a division of the presentapplication.
